Compute the determinant using a cofactor expansion across the first row. Select the correct choice below and fill in the answer box to complete your choice. (Simplify your answer.) O Using this expansion, the determinant is - (3)(-12) + (-2)(-6) - (4)(9) =. O Using this expansion, the determinant is (3)(-12) - (-2)(-6) + (4)(9) =. O Using this expansion, the determinant is - (-2)(-6) + (1)(-10) - (5)(-2) =. O Using this expansion, the determinant is (-2)(-6)-(1)(- 10) + (5)(-2) =
